Description

Technical Field

[0001] The present invention relates to the technical field of warehousing logistics, and in particular to a fast and automatic layout method of a warehousing logistics transportation system based on Unity3D and CAD. Background Art

[0002] As an important part of the logistics system, the warehousing logistics transportation system is responsible for the transportation of storage materials and the rapid circulation of materials in the warehouse. It not only affects the production efficiency of the enterprise, but also directly relates to the control of logistics costs and the improvement of service quality. Therefore, it is particularly important to quickly and accurately complete the layout of warehousing logistics transportation, and intuitively display the layout and simulation information of the warehousing logistics transportation system through three-dimensional visualization, digital twins, etc., which can improve the design of the layout of the warehousing logistics transportation system, improve material transportation efficiency, reduce logistics costs, strengthen security, improve warehousing management capabilities, and increase customer satisfaction, which will help promote the sustainable development of the enterprise and enhance the competitiveness of the enterprise.

[0003] CAD is computer-aided design software, which is widely used in two-dimensional drawing, design documents and basic three-dimensional design. In the field of warehousing and logistics, CAD is used to design warehousing and logistics solutions. Through CAD software, the various components of the conveying system can be accurately drawn, including conveying equipment, sorting equipment, shelves, etc., and their dimensions and attributes can be marked and defined. At the same time, the scheme drawings designed using CAD can provide basic data for subsequent simulation, animation production and virtual reality applications. Unity3D is an engine software widely used in game development, virtual reality, augmented reality and other fields. In the field of warehousing and logistics, Unity3D is more used to create digital twin systems. Through Unity3D, a virtual scene that is highly similar to the actual environment of warehousing and logistics is created, and the operation process of the logistics conveying system is simulated in it, realizing the three-dimensional visualization simulation and real-time interaction of the warehousing and logistics conveying system. Combining Unity3D and CAD can improve the design efficiency and accuracy of the warehousing and logistics conveying system, optimize warehousing and logistics management and warehousing systems, and is of great significance to promoting the intelligent development of the entire warehousing and logistics industry.

[0004] Although Unity3D and CAD play an important role in the design and layout of warehousing and logistics transportation systems, they are currently designed and produced independently. The integration of the two software is not high, and data integration and conversion are relatively complex. CAD software is mainly used for the two-dimensional drawing design of warehousing and logistics transportation systems. It is not possible to draw more complex three-dimensional models of transportation systems, nor can it be directly used for Unity3D. Although Unity3D supports the creation of three-dimensional models, it also does not support the editing of CAD two-dimensional drawings. Creating complex warehousing and logistics transportation system models requires in-depth script code knowledge and more manpower, energy and time to design and improve. It is impossible to quickly and automatically layout and create a transportation system. In addition, the accuracy and properties of the equipment model have great uncertainty, which brings certain difficulties to the subsequent production and simulation of digital twin systems. Summary of the invention

[0005] The purpose of the present invention is to provide a method for quickly and automatically arranging a warehousing and logistics transportation system based on Unity3D and CAD in order to address the problem that the data interaction between Unity3D and CAD is not high and the warehousing and logistics transportation system cannot be automatically and quickly arranged. The method can improve the layout efficiency of the warehousing and logistics transportation system. By combining the powerful visual editing capability of Unity3D and the precise solution data support of CAD, the layout of the warehousing and logistics transportation system can be completed quickly and automatically, thereby improving the layout efficiency of the warehousing and logistics transportation system.
